Replaceable license plate frame structure

Abstract

A replaceable license plate frame structure including a front frame and a rear frame in which the front frame is inserted. After assembly, the front decorative faces of the front and rear frames are flush with each other and together form a decorative picture or stripe. The rear face of the rear frame is formed with a peripheral dent for receiving a license plate. The front frame is formed with tenons and lugs and the rear frame is formed with corresponding mortises and lugs to engage the front frame, the rear frame and the license plate. Multiple front frame with different decorative front faces can be replaceably assembled with the rear frame so as to vary the pattern of the entire license plate frame structure.
